A Mental Health Unit officer is being credited with saving the life of a suicidal woman who threatened to jump off a tall building in Oshawa. It happened on Monday evening at around 5:00, when police were called to discover a 27-year old woman on the edge of the top deck of a parking structure. She was about 70 feet off the ground and had a rope tied around her neck. The officer talked to her for about an hour before she decided to come down off the ledge. She was taken for an assessment.
